Adjusting Front-to-Rear Leveling in Field-Hydraulic Leveling Motor

On machines with hydraulic leveling, a hydraulic motor (A) turns leveling control screw.

Use third tractor control lever to make front-to-rear leveling adjustment.

Hoses should be connected so that moving tractor control lever rearward raises front gangs (motor shaft turns clockwise) and moving tractor control lever forward lowers front gangs (motor shaft turns counterclockwise).

If machine is leaving a valley in center, move third tractor control lever rearward to turn leveling screw clockwise to raise front gangs and lower rear gangs-indicator (A) moves toward "E".

If machine is are leaving a center ridge, move third tractor control lever forward to turn leveling screw counterclockwise to lower front gangs and raise rear gangs-indicator (A) moves toward "A".

In some soil conditions, when a center valley cannot be eliminated, turnbuckle-to-link connection should be changed to rear hole. (See CHANGING TURNBUCKLE CONNECTION in Preparing Machine section.)

Indicator cable can be adjusted if desired by loosening attaching cap screw (B).
